ROTARY METER.

SPECIFICATION forming part of Letters Patent No. 298,230, dated May 6,1884.

Application filed September 1,51883. (No model.) l

To all whom it may concern.'

Be it known that I, JOHN A. PEER, of Grass Valley, in the county ofNevada and State of California, have invented a certain new and usefulImprovement in Meters, also applicable tok Motors and Pumps, of .whichthe following is a specication. v

The nature of this improvement will be fully described, and then pointedout in the claims.

In the accompanying drawings, Figure l isV a section of an articleembodyingy my improvement, taken transversely to the axis; and Fig. 2 isa section of the same taken parallel with the itXlS.

Similar letters of reference designate corresponding parts in bothiigures.

A A A2 designate the case of the article, consisting, as here shown, ofa cylindrical shell, A, and heads A A2. The shell and heads are shown ashaving radially-extending fianges secured by screws. Any suitablepackings may be employed to preclude leakage between these parts. Thehead A is provided with an outwardly-extending cylindrical neck, A3,onto the exterior of which is secured a frame, B, and the head A2 isprovided with a cylindric shell, A4, that extends inwardly into theshell A almost to the head A. This head A2 also is provided with anoutwardly-extending air-chamber,V. The shell A4 is provided with holes athroughout about one-half of its The air chamber ,V is provided with anOutlet, a- The lower portion of the shell A is provided with atangential inlet tube or passage, A5, that may be formed therewith, ormade separately and screwed thereto, so as to communicate with anopening through the shell. The fluid which is to be passed through thecase enters through the inlet-tube A5, and escapes from the said casethrough the holes a into the shell A4, and thence through the hole a ofthe air-chamber A4. If the iiuid is to be saved, the hole ce of theair-chamber V may be connected with any suitable conduit or reservoir.

C is a rotary shaft, which, as here shown, is journaled at one end in ahollow screw, D, insei-ted in the outer end of the frame B, and at theother end in a hollow screw, D', inserted in the outer side of the.air-chamber V. The.

shaft O has affixed to it a wheel, E E E2 E3,

consisting of two heads, E E', and two series of blades or buckets, E2E3. The` buckets E2 extend at an angle both to the radii andcircumference of the heads of the wheel inward a short distance from thecircumference of these heads. The buckets E3 extend from a point closeto the inner ends of the buckets E3 close to the shell A4. The bucketsE2 will preferably be curved, but may be approxi- 6o mately straightfrom end to end. The buckets E3 are shown as curved eccentrically to theheads of the wheel and to the shells A A4. A cylindric shell, A3,extends fromV the head A2 between the buckets E2 E3, and into a 65groove, c, in the head E of the wheel. It may be made separately fromthe head A2, and secured thereto by screws or otherwise. In the upperportion it is provided with a hole, d. The outer ends of the buckets E37o extend close to the shell A.v llhe wheel has a hub, E4, that` extendsinto the neck A3 of the head A. The neck A3 is provided at the outerVend with a cap, A3, that closes it. It may be advantageously providedywith a stufling-box, through which the shaft C will pass.

All the parts described may be made of metal.

Preferably the inlet-tube A5 will be provided with a cock, e, forregulating the quan- 8o tity of fluid passing through it. Fluid enteringthe inlet-tube A5 passes into the case, and, acting against the bucketsE2, imparts motion to the wheel.` Moving in contact with these buckets,and between the shellA and the shell A3, it finally reaches the openingd ofthe shell A3. Passing through this opening,it comes in contact withthe buckets E3, thereby imparting an additional impetus to the wheel.After acting against the buckets E3, it enters the shell 9o A4, andescapes through the same. By passing fluid under pressure thus throughthe article described, it will be measured, and will render the articleuseful as a motor. If the wheel be rotated by power applied to itsshaft, fluid will be pumped through the article. Obviously the articleis therefore a meter, a motor, or a pump, according to the manner inwhich it is used.

When the apparatus is to be used as a meter, Ioo the shaft C may beprovided with an index, forming part of a registering apparatus, or

with a bevel-wheel that may engage with another bevel-wheel on the shaftof the index of a registering apparatus. The registering apparatus maybe ot'any well-known character.

5 Vhen the apparatus is to be used as a pump,

motion maybe imparted to the shaft C by belt or other gearing.

Vhen an index is to be operated, the shaft of the index may extend aconsiderable dis- Io tance from the meter-as, for instance, from acellar to a sidewalk above it.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a meter, motor, or pump, the combirs nation of a case, a wheeladapted to rotate within the same, and having two sets of buckets, acylindrie shell extending between the two sets of buckets of the wheel,and having an opening through which fluid may pass from 2o the outer setof buckets to the inner set of buckets, and an outlet from that portionof the case which is surrounded by the inner set of buckets,substantially as specified.

2. In a meter, motor, or pump, the combi- 25 nation of a case, a wheeladapted to rotate within the same, and having two sets of buckets, acylindric shell extending between the two sets of buckets of the wheel,and having an openin g through which iiuid may pass from the outer setof buckets to the inner set of 3o buckets, and a shell extending intothe central part of the case and serving to convey away iiuid therefrom,substantially as specified.

3. In a meter, motor, or pump, the combination of a case having atangential inlet tube 35 or passage communicating with the lowerportion, a wheel adapted to rotate within the case, and having two setsof buckets, a cylindric shell extending between the outer set of bucketsand the inner set of buckets of the wheel, 4o and having an openingthrough which iluid may pass from the outer set of buckets to the innerset of buckets, and an outlet from that portion of the case which issurrounded by thev inner set of buckets, substantially as 45 specified.
